Crow Wing County Geologic Atlas, Part A, County Geologic Atlas Series C-16, published by the Minnesota Geological Survey, 2004. More information and downloadable data for Part A available on the MGS ftp site.

This file was made with water level information from two general sources : driller’s logs from the County Well Index (CWI) database managed by the Minnesota Department of Health and the Minnesota Geological Survey with verified locations and measurements by DNR staff in conjunction with well sampling for this atlas project. The driller’s log data were obtained from the CWI database and represent a data set that was collected over a period of several decades and spans seasonal and multi-year climatic trends of wet and dry conditions. Where the dataset included both CWI drillers log information and water levels collected by DNR staff, the DNR data were used. Todd Petersen created the potentiometric surface of the aquifers by labeling the water elevation values next to the well locations in Arc GIS 9.2 with both a topographic DEM and a topographic map as background layers. Water elevations were drawn by Todd Petersen as 25-foot line contours by digitizing on-screen using the land topography as a guide in areas where data were scarce.

This map was prepared from publicly available information only. Every reasonable effort has been made to ensure the accuracy of the factual data on which this map is based. However, the Department of Natural Resources does not warrant the accuracy, completeness, or any implied uses of these data.
